Many technologies can harm the environment:
Carbon dioxide and carbon monoxide are greenhouse gasses that are produced by people. Greenhouse gasses in the atmosphere trap and reflect heat and radiation back to the planet's surface and contribute to global warming.
Carbon emissions get released into the atmosphere from cars, airplanes, power plants and factories. They also get released by burning fossil fuels to create energy.
Technotrash, also called electronic waste or e-waste, is any broken or unwanted electrical or electronic device, and is currently the most rapidly-growing type of waste.
Technotrash thrown out with the regular trash usually ends up in a landfill. Most electronics contain non-biodegradable materials, and heavy metals and toxic materials that can leak into the ground. They can contaminate the water we drink, the plants we eat, and the animals that live around the area. These toxic materials can cause nausea, diarrhea, vomiting, and even cancer.
