COVID Vaccines and other Concerns

I’ve been involved in arguments over COVID vaccine safety. The concerns might be valid, but they might not. Assessing the mountain of facts and opinions could take months or years. There are more worthy issues. Human population is too large, pollution of all kinds including CO2 mentioned in the linked article, is excessive, and wild plant and animal numbers are falling. Survival of Earth’s ecosystems is threatened, and this seems like a more important topic of conversation than the possible loss of a few humans because our public health system might be corrupt.
