Solving environmental problems is expensive and the financial burden on governments alone is too high. As businesses are often responsible for causing some of the environmental problems, they should help with the cost of solving the problems. This could be done by contributing funds or by implementing new systems to minimise further pollution.
A second reason that solving our environmental problems requires joint contribution is that action and effort are needed. The government can spend money on campaigns or introduce taxes; however, slowing or stopping the problems requires effort from all. If businesses do not stop polluting and individuals do not minimise their waste, no advertising campaign will be effective.
Admittedly, the government does have the power to make an enormous impact on the environment and without government intervention change would probably not happen. The introduction of the carbon tax in Australia is an example of government action helping solve environmental problems. However, without all parties contributing this change would not be effective.
