1 . Our recommended list of environmental books covers a broad range of topics. These must-read environmental books are sure to spark the interest of the greenest books.

Silent Spring

Written by Rachel Carson, Silent Spring highlights the effects of pesticides (杀虫剂) on the environment, especially DDT, which was a very popular insecticide until it was finally banned in 1972. The book eventually led to a change in the United States’ pesticide policy and contributed to the creation of the Environmental Protection Agency.

No One Is Too Small to Make a Difference.

This book collects 11 speeches made by climate activist Greta Thunberg, highlighting the issue of climate change and its impact on future generations. Greta Thunberg was 15 when she started the School Strike for Climate, also known as Fridays for Future. She inspired protests worldwide.

The Uninhabitable Earth

This book by David Wallace Wells examines the disasters that have already occurred and looks ahead to the year 2100 and what climate change will do if we continue on our current path. Its opening line is incredibly telling: “It is worse, much worse, than you think.”

The End of Nature

Published in 1989, the book describes the relationship between nature and humans. It expresses the idea that nature was previously independent of humans but has now been affected by them in every way. According to author Bill McKibben, the idea of wilderness is lost, and nature is no longer complete.

6 . There’s been growing concerns about the damaging impact of human travel on the environment in recent years. Irresponsible tourism is a main cause of environmental destruction. The destruction of the natural environment is an urgent matter as it directly affects everyone’s well-being.     1     As a student passionate about travel, you should leave as little carbon pollution as possible wherever you visit.

Avoid takeaways as many as possible

Buying “food to go” seems logical when you are in a rush. Though convenient, this kind of take-out packaging often uses disposable(一次性的) plastic boxes and bags, which can contribute significantly to environmental pollution if not properly disposed of.     2     You can, instead, eat out in a restaurant while enjoying a scenic atmosphere. If you have to take away something like coffee, use a reusable cup.

Go for train or bus when traveling nationally

Transportation accounts for nearly a third of all greenhouse gases produced in the environment. Flying and driving, in particular, are major contributors to carbon emissions(排放) within the transportation sector, with domestic flying emitting more carbon than driving.     3    

Stay on designated roads and foot paths

Responsible tourism is about having as minimum physical interaction with the wild as possible. We not only protect the fragile ecosystems around us but also ensure our own safety.     4     If you stray away from designated(指定) paths, you risk damaging plants and the natural habitat for animals.

Pick up trash after yourself and others

    5     Instead of dropping trash, why not pick it up? You can significantly impact the environment by picking up trash along trails when hiking or backpacking for proper disposal.

In conclusion, responsible tourism is traveling with awareness, respect, and consideration for the places you visit. It’s about ensuring that your travel experiences enrich not only your own lives but also contribute positively to the destinations you explore, leaving them better than you found them.

10 . To produce the classic clothing, blue jeans, producers rely on indigo dye (靛蓝染料), the only molecule known to provide jeans’ unique, beloved color. While indigo itself naturally comes from a plant, growing demand for blue jeans throughout the 20th century gave rise to synthetic (合成的) indigo, which is now more commonly used.

Indigo is the dye that makes jeans blue, but it doesn’t mix with water. To dye clothes, usually, chemicals are needed to make the color stick to the cloth. But in Denmark, scientists have created a new way to dye clothes using an enzyme (酶), which is a kind of protein that can cause chemical reactions, instead of harmful chemicals. This new method is better for the environment and doesn’t use poisonous stuff.

The chemical process for dyeing blue jeans has persisted for the last century. Workers are exposed to the poisonous chemicals, which also pollute the environment near factories. Waste water from those factories often ends up in waterways, decimating local ecosystems and even dyeing rivers blue.

Ditte Hededam Welner, the study’s lead researcher, says their new enzyme works really well and is strong enough for making lots of jeans without breaking down. This enzyme makes dyeing with indican, which is like indigo, much less harmful to the planet — about 92% better than the old way.

However, the new method doesn’t fix all the environmental problems of making jeans. Making a single pair of jeans uses a lot of water — enough to fill many bathtubs — from growing the cotton to putting the final touches on the jeans.

Even though the new dyeing process is better for the environment, it’s not always easy or cheap to change to it. Welner’s team isn’t sure if jeans companies will find it easy or affordable to switch to this method. It costs a little bit more — just seven cents extra per pair of jeans — to use the enzyme for dyeing. But Welner believes it’s worth it because it’s much better for the environment.
