Environmental terrorism is when people intentionally harm the environment to make a political or social point. Imagine you have a beautiful garden with flowers and trees, and someone comes and cuts down all your plants just because they want to get your attention or make you do something. That's like what environmental terrorists do, but on a larger scale.
For example, some people might set fire to a factory that they think is polluting the air or water, or they might release dangerous chemicals into a river to protest against a company that is not following environmental rules. While it may seem like a way to bring attention to an issue or cause, it is a very dangerous way to do so, as it can harm innocent people, wildlife, and the environment itself.
Environmental terrorism can also include things like hacking into computer systems to steal or destroy data related to environmental issues or breaking into facilities to sabotage equipment. It is important to address environmental concerns and work towards solutions, but using violence or causing harm is never an acceptable approach.
