Environmentalism is caring for our planet and all living things in it. It's about taking steps to make sure we don't harm nature.
We often hear people talking about environmental issues on the news or in conversations, and they might mention something like "I'm concerned about climate change" or "I love recycling because it helps protect the environment." People who really care about the Earth might call themselves environmentalists. They try to live in a way that doesn't hurt animals, plants, and water, and they want others to do the same. For example, someone who chooses to buy products with minimal packaging is being environmentally friendly – or an environmentalist.
A theory that views environment, rather than heredity or culture, as the important factor in the development of an individual or group.
