It just so happens that billions of people believe in this random individual from several thousands of years ago. He promised to destroy the world again, when He returns (which could be any day now)
The last time He killed billions of men women and children with a flood, this time He is going to use super hot lava. He promised to melt the whole earth and kill everything on it, then He will create a brand new world, so this is why I don't care about pollution or climate change, it's just as wise as rearranging the deck chairs on the Titanic while it sinks.
However, I find it it is the world of badness and Not the literal Earth. Remember: Earth abides forever - Ecclesiastes 1:4 B.
Not super-hot lava but as Isaiah wrote at Isaiah 11:3-4 it will be the -> 'executional words from Jesus' mouth' to destroy the wicked.
Jesus with angelic armies - Revelation 19:15.
Please notice how Jesus will act at the soon coming time of 2 Thessalonians 2:7-8.
For the false religious leaders are the composite 'man of lawlessness' the ' son of perdition' - 2 Thessalonians 3:-4
They (he) seats himself in the ' temple ' (houses of worship) as if he is God when in reality they the ones who are anti-God.
I find we are to show we care about Earth (Genesis 1:28; 2:15) thus we can show we even care by Not littering.
This does Not mean we take up Earth Day worship causes that are often too BIG to handle.
That would be like you say, " rearranging the deck chairs on the Titanic while it sinks." (<- that's a good one !)
Rather, we are to focus about telling the world about God's kingdom (Daniel 2:44) just as Jesus said to do at Matthew 24:14; Acts 1:8.
Instead of lava, I find we are facing a soon coming ' time of separating ' on Earth as described at Matthew 25:31-33,37.
Not Earth removed or damaged, but the figurative haughty ' goats ' removed or perished - 2 Peter 3:9
