Basketball is a team sport. A team consists of five positions: point guard, shooting guard, power forward, small forward, and center. I'm going to focus on the point guard (PG); the point guard's job is, essentially, to generate scoring by passing the ball to the teammate in the best scoring position or score himself if possible.
My favorite PG is Stephen Curry, so I'll use him as an example. Curry averages 25.3 points a game. This is a respectable number, however, Curry can't win the game all by himself, which is why his job entails getting the ball to other scorers. Let's say Curry plays his heart out one night: he scores 40 points and distributes the ball, but none of his teammates put any effort in. The result would be a loss due to lack of teamwork. If this happens night after night for a season or two, then Curry would probably be looking for another team.
The Paris Climate Agreement was intended to be a collective effort to stop climate change, which is unrealistic anyway. The US is like my example above. We payed "$1 billion to the global Green Climate Fund, but the world's top polluters contributed nothing". The US is doing all the work while other countries aren't doing anything.
I'm relieved that Trump pulled us out of the Paris Climate Agreement. This Agreement was another example of the U.S. being taken advantage of by countries who don't want to do their part, as mentioned above. China is one of the nations that hasn't put any money into the fun, have you seen the smog over there? If climate change were real, then China would be the biggest threat to the climate.
I also have a personal dislike of the Paris Agreement, because I don't believe climate change is real. I agree with Trump that climate change is a hoax. I know I may sound ignorant about my doubt of climate change, however, I do research on climate change frequently. I'm still not convinced. Here's a link to the best article refuting global warming I've read: http://www.justfacts.com/globalwarming.asp#pageTitle
I would rather our country spend money on real problems like, defense against terrorism and radical countries (N. Korea), the education system, the national debt, illegal immigration, and crime rates. And there's plenty of other problems in addition to those few examples.
