When reading your page [The Weekend Sun, page 2, July 26], particularly about Ollie Langridge making a stand on a national climate emergency, I could not help wondering why such people don't do some research on the subject. Ever since the world came into existence, climate change has been through thousands of cycles of many different types, triggered by many different causes, and so many species of every type of plant and animal have ceased to exist. All have finished their cycle of existence through some means.

Nothing lasts forever; the most constant effect on this earth is change – nothing stays the same. Why can't the drum-bangers realise this and accept that this is a natural phenomenon and we should not expect the species living in our short life-time to co-exist with us. Birds and animals have a shorter life-span than us, and it makes sense that their evolutionary span of existence is also shorter. Humans waste so much time and money in trying to breed more of the disappearing species, when they should be using such funds to help their fellow humans live in less hardship. Giving help to one's own species' survival makes better economic sense.

You only have to look at historical events, such as the biggest recorded volcanic eruption of Mt Tambora in 1815, to see the cataclysmic effect that had on global cooling, initially, through to 1817, which wiped out food crops for several seasons, plus insect, bird, animal and human population because of the heavy ash falling, but for years afterwards the lingering fine particles of ash that floated in the stratosphere, were blown far and wide by winds, blocking solar energy. People in those days had no means of knowing what caused their hardship, but now Wikipedia can tell us.

Mankind may be irresponsible about dumping their waste thoughtlessly, and we can certainly address that, but they are not responsible for everything and cannot change nature, therefore we should be able to accept leaving God's work to him. He made this world, and can also unmake it at any time, if our own messes overwhelm us.
