1 . Shop Sustainably

If you have to name one thing that contributes most to your ecological footprints, you may say the energy you use at home, or your car’s emissions.     1     Knowing this can make your grocery shops more planet-friendly. Here is what you can do to help shop sustainably.

●    2     Using those is a great first step. If you get some, do remember to fill them with your purchases. When you adapt yourself to reusing them, then you’ll cut your consumption of single-use plastic bags even further.

●Avoid unnecessary packing. Buy loose fruit and vegetables instead of pre-packaged produce, and avoid products that contain multiple single packages or double packaging, like grain in a box and a bag. Consider switching from tea bags and coffee pods to tea leaves and ground coffee.     3    

●Go organic when you can. In addition to the benefit organic farming has to insect biodiversity, it’s also considered more sustainable and better for the environment.     4    Choosing free-range or Marine Stewardship Council-certified products also encourages environment- and animal-friendly food production.

●Buy seasonal and native products.     5     So you can avoid buying goods that have travelled long distances to reach your plate. As well as opting for local goods, depending on where you live, in the supermarket, you can also buy directly from the source at farmers’ markets.

2 . Say No to Non-electric Cars

Most modern cities have taken action to reduce traffic jams and improve air quality. But if they want to become more livable, they should think about more ambitious goals.

Amsterdam has set a good example. As from 2030, driving a gas vehicle there will not be allowed. The Dutch capital wants its citizens to become healthier and happier.    1    Amsterdam isn’t alone; it joins Hamburg, Madrid and other cities in moving toward at least partial car bans to reduce pollution.

The advantages of such plans are clear.     2    It slows economic growth. Pollution from cars not only contributes to climate change but is also a threat to well-being. Amsterdam’s government says it reduces life expectancy of its citizens by a full year.

    3     Electric cars, after all, are more expensive. And for most people, giving up driving means life will become less convenient. Perhaps cities can help make this switch easier. For example, they can think about improving public transportation. They can also design appealing public spaces for pedestrians (行人).     4     Technology can also do its part. Cities can be more open to new ways of getting around, such as bike-sharing, driverless cars and delivery drones(无人机).

Saying no to non-electric cars or even all cars is hard.     5     Making our cities more livable has to become an urgent goal.

3 . Animal and plant species are disappearing at frightening rates. The problem has led to efforts to “rewild” places where such life existed before human development, pollution and climate change forced it out. The American city of Detroit is an example of how human actions can increase rewilding, which generally means helping natural systems in damaged locations, removing dams or building tunnels to reconnect animal pathways cut by roads.

Detroit’s population reached a high of 1. 8 million in the 1950s. Then the population began dropping. By 2000, there were fewer than one million people living in the city. Thousands of houses and other buildings were left empty over the years. Some structures were destroyed, leaving empty areas that plants and animals regained as habitats. Nonprofit groups have also planted trees and community gardens in these areas. Bald eagles found their way back as bans on DDT and some other insect poisons were put in place nationwide. Anti-pollution laws and government-supported cleanups made nearby rivers better for fish and native plants.

Now, Detroit is home to 300 bird species and is a busy visiting place for ducks and others during migration. Additionally, this city offers a special way to study plants and animals in urban settings. Unlike most big cities, its population is decreasing but its streets and buildings remain in place. And there are many kinds of habitats, including large lakes, rivers and human neighborhoods. Detroit’s parklands are so quiet that people don’t even know they’re in the city.

“It used to be that you had to go to some remote location to get exposure to nature,” said John Hartig, a professor of University of Windsor. “Now that’s not the case. Like it or not, rewilding will occur. The question is how we can prepare communities and environments to anticipate the presence of more and more wildlife. After all, many city people have lost their tolerance to live with wildlife. To really make a difference in dealing with the biodiversity crisis, you’re going to have to have people on board. ”

5 . As environmental concerns continue to increase, many people are left wondering how they can balance the need to travel with the need to protect the planet. One particular dilemma that has received significant attention is air travel.

Air travel is known to be one of the most carbon-intensive forms of travel. According to a report by the European Environment Agency, aviation is responsible for around 3% of the EU’s greenhouse gas emissions, and that number is expected to grow in the coming years. In addition, aircraft contribute to other types of air pollution, such as particulate matter and nitrogen oxides.

For environmentalists who advocate for reducing our carbon footprint, this brings up a difficult question: should we avoid flying altogether?

On one hand, it’s easy to see why environmentalists would want to keep away from air travel. By doing so, they could dramatically reduce their carbon footprint and set an example for others. Additionally, some argue that air travel perpetuates(使永久)a culture of overconsumption, which is contradictory to environmental values.

However, there are also arguments in favor of air travel: For one, air travel enables people to experience different cultures, build relationships, and expand their knowledge in ways that might not be possible otherwise. It can also facilitate business trades and contribute to economic growth. Moreover, some experts believe that technological advancements could make air travel more sustainable in the future. For example, some airlines are experimenting with biofuels and electric planes, which could dramatically reduce the emissions associated with air travel.

So what’s the answer? Ultimately, it’s up to each individual to decide whether the benefits of air travel outweigh the environmental costs. However, there are steps that everyone can take to reduce their impact. For example, travellers can choose to fly less frequently, opt for direct flights, and offset(抵消)their emissions through programs like carbon offsetting. In the end, the key is to remain aware of the environmental impact of our choices and to make informed decisions based on our own values and priorities.

7 . On August 8, 2021, the United Nations’ Intergovernmental Panel on Climate Change (IPCC) released its first assessment of climate science since 2013. The news was not good. The report stated that this past decade was the hottest in 125,000 years and that the atmospheric carbon levels are the highest in at least 2 million years. Glaciers are melting faster than any time in over 2,000 years, and ocean levels are rising at twice the rate since 2006.

At the current pace, the researchers expect global temperatures to rise by at least 1.5°, compared to pre-industrial levels, within the next 20 years. The temperature increases will result in significant changes to the planet’s water cycle. Areas that currently receive a lot of rain will get significantly more, while dry regions will become increasingly likely to droughts.

The IPCC’s findings come as no surprise to the millions of people worldwide currently feeling the impacts of climate-related disasters. America and many European countries are battling wildfires. Meanwhile, an unprecedented (史无前例的) week-long storm in July 2021 caused flash floods and mudslides in Western Europe. Climate change is even impacting the Earths coldest and most remote regions which experienced the first rainfall event in recorded history.

The situation may sound hopeless. However, many experts believe it is still not too late to turn things around, if we all act now. While governments need to do their share by introducing and obey stricter carbon emission laws, individuals can also help. Driving less, conserving water, and reducing electricity usage are some great ways to start. Reduce, Reuse and Recycle will help conserve natural resources and energy. It will also save you and your community. Be sure to start doing your part to save our beautiful home today!
