What does "environmental protection" mean to you
What does "environmental protection" mean to you
For us, environmental protection means reducing waste. We can start by using reusable bags instead of plastic ones, and recycling paper, bottles and cans. These small actions can make a big difference to our planet.
Environmental protection is about protecting wildlife habitats. When we cut down forests or pollute rivers, many animals lose their homes. We should support conservation projects to safeguard these precious habitats.
Watch and think: how does environmental degradation impact human health
Phrases and Idioms
This is a well-known environmental slogan. “Reduce” means to minimize the amount of waste we produce by consuming less. “Reuse” involves using items again instead of throwing them away, and “Recycle” is about processing used materials into new products.
When grocery shopping, we can reduce the use of plastic bags by bringing our own reusable bags.
Reduce, Reuse, Recycle
减用，重用，再利用
We can reuse glass jars as storage containers.
And we should recycle paper, cardboard, and plastic bottles at designated recycling bins.
Phrases and Idioms
It is an expression that encourages people to adopt more environmentally friendly lifestyles. It encompasses a wide range of actions, from using energy-efficient appliances to choosing sustainable transportation.
A person can "go green" by switching to LED light bulbs to conserve energy. Or they can choose to bike or take public transportation instead of driving a gas-guzzling car, which helps reduce carbon emissions.
Go Green
采用环保措施
Phrases and Idioms
This phrase emphasizes the urgency of taking action to protect the planet from environmental threats such as climate change, deforestation, and pollution. It implies that collective efforts are needed to preserve the Earth for future generations.
Communities can come together to plant trees to combat deforestation and help absorb carbon dioxide. Nations can work towards reducing their greenhouse gas emissions to slow down global warming, all in
the name of “saving the Earth”.
