termites
one of the arguments against anthropomorphic climate change is that the earth is so frikken huge people can't possible affect it. that's an absurd position on its face. but we don't take things for granted here. we're scientistas! so let's do some maths. the earth is infested with 7 billion tiny little bags of meat. suppose my house were infested with 7 billion termites. with a little help from google, i calculate they could eat my house in its entirety in about 2 weeks. they could eat 25 of my houses in a year. that isn't very many considering there are more than 100 million houses just in the us. it'd take them 4 million years to eat them all. course termites don't have to eat the entire house. if they ate only 10% it'd be effectively destroyed. and if they ate only 1% it'd be damaged. okay, so 40,000 years to damage every house in the us. humans aren't really termites. termite destruction is limited to what the termite can eat. literally and thermodynamicly. ie termites are powered by what they eat. humans utilize external energy sources to make them more like super termites capable of "eating" 100x more than they eat. 7 billion super termites can damage every house in the us in 400 years. we've been super beings since about the dawn of the industrial age. about 150 years ago. so yeah, it's not at all surprising that we're seeing damage to our habitat. it might not be obvious. but you can see the termite trails if you look. or you can ignore it. for a while. til your house falls down.
