On a macroscopic level there is nothing we can do to stop the march of time. As the old saying goes if Heaven and Earth cannot make things eternal, how can man?
But denying we have not had any effect on a microscopic level is ludicrous. You can ignore the science and just turn on the news to see what is happening to the environment. ‘Climate Change’ is probably the wrong description. The more alarmist ‘Environmental Collapse’ would be more appropriate given the circumstances.
Taken on that account we can see how plastic pollution is hurting wildlife and how dumping sewage into rivers and oceans is a bad idea for all involved. There actually might not be much we can do to stop the worst of it now we have passed certain tipping points which is why investment in cleanup technologies is paramount.
Just Stop Oil has a point but it’s more about conserving what’s left of our dwindling fossil fuel reserves for meaningful manufacture than plastic tat. Investment in renewables allows us to localise energy production without making cities or towns worse and provide blue collar jobs with a minimal commute. It also provides countries with energy independence, a valuable asset in increasingly unstable times. But we need hydrocarbons for the manufacture of the infrastructure so just completely stopping oil extraction would be suicide.
