What environmental protection measures are needed?

Living organisms need a habitat. We need oxygen, food, water.
In our time, this is a problematic issue. The environment is polluted, ozone holes, fresh water is decreasing, global warming, soils are full of pesticides.
From all these problems, it follows that humanity should reduce the level of exhaust emissions, take up greening of roadside areas, reduce deforestation and stop polluting the soil. And also switch to alternative types of electricity.
