Students need to address the depletion of natural resources and waste management. Natural resources are being depleted faster than they are being replenished.
Cars are heavy polluters of the environment.
Economics always seems to be more important than the environment so until gas prices become too high we will always drive in gas-powered cars. As an alternative source of energy, solar power can't be beat. It provides zero emmissions and works as long as the sun shines. To maximize energy output a solar array or grid needs to be placed in orbit to collect energy from the sun 24 hours a day. Waste management is a huge issue that needs to be addressed now.
