1 . Organic food is very popular. It is also expensive. Some organic food costs twice as much as nonorganic food. Some parents and pet owners pay up to 200 percent more for organic food while some people think organic food is a waste of money.
There is one main difference between organic and non-organic food. Organic farms do not use agricultural chemicals, such as pesticides (杀虫剂). This makes sure that the products are natural.
Some people think “organic” means “locally grown”. At the beginning, this was true. Over time organic farming became more difficult. The demand for organic food grew larger than the supply. Small companies had to sell out to large companies. There weren’t enough organic materials. This made it difficult for many organic companies to stay in business. Today, many large companies have an organic line of products.
Is organic food more nutritious? This is part of the debate. Many farmers and consumers believe it is. They think agricultural chemicals cause health problems, such as cancer. Many health experts disagree. Few studies prove that organic food prevents health problems. Health experts worry more about bacteria. These can come into contact with organic and non-organic food. Doctors recommend washing produce very carefully.
Most people agree that naturally grown food tastes better. Is tastier food worth the extra money? This is a matter of opinion. Whether it is healthier or not may require more research. However, organic consumers argue it is better to be safe than sorry.

2 . Air pollution is the world's top killer, a new global air quality index revealed last year. According to the World Health Organization(WHO), 4. 2 million people die each year from outdoor air pollution, and 91 percent of the world's population lives in a place that exceeds the WHO's guideline limits. With that in mind, Imperial College London has teamed up with biochemical tech startup Arborea to test out its biosolar leaf technology, while also demonstrating how sustainable solutions can address the vital environmental and social issues of today in real-world conditions.
So, what is a biosolar leaf and how does it work? The secret is algae(海藻). Arborea researchers developed a cultivation(培养)system that allows microscopic plants like microalgae to grow on large solar panel-like structures that can be installed on land, buildings, and anywhere with a roof in a built-up city to improve the surrounding air quality. Inspired by the natural process of photosynthesis(光合作用),the biosolar panels allow the microorganisms to absorb CO2 from the surrounding area and generate breathable oxygen back out again. And they help produce a nutritious, sustainable plant protein with tiny environmental impact—— Arborea's other focus——at the same time. "When I founded Arborea? my goal was to cope with climate change while addressing the critical issues related to the food system," Arborea founder and CEO Julian Melchiorri said. "This pilot plant will produce sustainable healthy food additives while purifying the air, producing oxygen and removing carbon dioxide from the surrounding environment.”
Melchiorri has already had some success with his astonishing project, the world's first living bionic chandelier(仿生吊灯),which uses the same technology. The light of the chandelier stimulates photosynthesis of the microorganisms on the leaf-shaped modules, absorbing the CO2 inside and releasing oxygen back into the room. The chandelier currently holds pride of place in London's Victoria and Albert Museum's permanent collection.

3 . As the world's resources become rarer because of continuing land development and the growing human population, the natural habitats of wild animals have continued to decrease. As a result, the survival of some species of wildlife is threatened. To help protect wildlife, a lot of practices should be carried out by environmentalist as well as the general public.
Create homes for species that are endangered because of losing their own natural habitats. Wildlife shelters should be developed, and habitats should be created in existing(现存的) national parks. Efforts(努力) should also be made to protect existing habits, such as providing food and water sources and limiting hunting. Breed(培育) endangered species in places such as zoos. Once the young animals grow up, they can be set free into the wild where they can continue to increase the population.
The general public may not realize that a species is endangered until it's too late. Educational programs making use of TV advertising and instructional meetings at national parks can be used to make the public know the situation.
The general public can help protect the wildlife by not hunting wild animals for sport or for a source of food. They should also stop supporting those who earn money from the illegal hunting of wild animals, such as hunters who kill animals for the only purpose of harvesting their body parts and selling them for money.
The public should avoid(避免) keeping wild animals as pets. This will limit the number of animals being tracked, trapped, sold and removed from their natural habitat.

6 . Backcountry for beginners: the best destinations in Canada
When carried out safely, your first backcountry trip will leave you lifelong memories, opening a getaway into nature. But the leap from car camping to backcountry requires preparation and learning. Here are some recommended trips for backcountry beginners:
Grundy Lake Provincial Park
The park’s 9 backcountry sites are a 30-minute paddle (划船) away. Grundy Lake is motor-boat free. Your sites are quiet enough for a true backcountry trip. Each site comes equipped with a fire pit (坑) and a picnic table.
Bon Echo Provincial Park
Many visitors don’t know about the 25 canoe-in campsites located on Joeperry and Pearson Lakes. A short canoe trip of 30-minute will get you to your campsite. At each campsite, you will find a picnic table, tent space and a toilet nearby.
Charleston Lake Provincial Park
Experience the best of the Canadian Shield, and hike or paddle your way to 10 backcountry campsites. Travel time can range from 10 minutes to 2 hours. All sites come equipped with elevated tent platforms, a picnic table, a fire grill, and a toilet.
Murphys Point Provincial Park
Paddle through Big Rideau Lake (part of the historic Rideau waterway) to access 14 backcountry campsites. Most are located 5-45 minutes away from the boat launch. You’ll find a picnic table, tent space, and a pit toilet nearby each site. Paddle back to visit Murphys’ piece of living history: the Mica Mine!
Remember: backcountry travel requires careful consideration of packing, route planning, meal planning, safety, and your skill level.
