An environmental issue is a problem or situation that affects the natural world around us. It can be something that humans are doing, like polluting the air or water, or something caused by nature itself, like a hurricane or drought. These issues can harm the plants and animals that live in our world, and also affect human health and well-being. Some environmental issues include things like climate change, deforestation, and pollution. It's important that we all work together to take care of our planet so that we can continue to live here for a long time. That means using resources responsibly, like recycling and conserving energy, and making changes to our behavior to reduce the negative impact we have on the environment.
