As an illustration
Bearing in mind that the greenhouse gas CO2 takes around 1,000 years to break down naturally (retention time), only a long-term reduction of greenhouse gases can protect the climate. The coronavirus crisis is posing problems for other parts of the environment too: The United Nations are reporting that the volume of non-recyclable waste has risen significantly across the world. An increase in illegal forest clearances and fishing has also been reported given that environmentalists can no longer take action on-site.
The coronavirus crisis will not protect our environment on a sustained basis; the protection and respectful treatment of the environment as a resource will require a long-term approach.
