When I thrive, you thrive. When I falter, you falter, or worse. But I’ve been here for aeons. I’ve fed species greater than you, and I have starved species greater than you. My oceans. My soil. My flowing streams. My forests. They all can take you, or leave you. How you choose to live each day, regard or disregard me, doesn’t really matter to me, one way or the other. Your actions will determine your fate. Not mine. I am Nature. I will go on. I am prepared to evolve. Are you

What an Adventure!
It’s been three days since I got separated from the other team members. We went hiking together on Monday, but became separated due to a heavy rainstorm. Without a compass, I lost direction, and now I am lost in dense jungle.
There are no roads at all, so I have to make my own way step by step. I have hurt both my hands quite badly from all the thorns – they are everywhere. To make things worse, I stumbled and sprained my ankle. The pain is killing me! Snakes, monkeys, insects and other animals appear from time to time. Yesterday, I heard the roar of a tiger from far away. I was terrified! I rub sticks together to make a fire every night to keep myself warm and safe. It’s really a difficult technique to master, and it takes me several frustrating and worrying attempts every evening. I have to remind myself to be calm and optimistic at every moment.
Food also worries me a lot. I’ve been eating berries to appease my hunger, but I have to be very careful to avoid anything poisonous.
Today I have some luck when I find a stream which I can follow. It gives me great hope. I’m confident that I can find my way out! This will have been the most memorable adventure of my life!
