Its bigger than Texas and growing. The way to clean it up now is to catch it with nets. That is both costly and slow. Instead, the Ocean Cleanup Project proposes a 62-mile-long floating barrier that would use natural currents to trap trash. If next years trials succeed, a full cleanup operation would aim to start in 2020. It could reduce the trash by 42 % over 10 years.Easy-On ShoesIn 2012, Matthew Walzer, a high school student with a disability, sent a note to Nike. “My dream is to go to college,” he wrote, “without having to worry about someone coming to tie my shoes every day.” Nike assigned a design team to the challenge.

Sometimes I wondered, lying awake at night, how many hearts beat inside those walls. With all that lovely national park habitat protected for their use, why did the animals need to live in my house?My latest essay “The indoor wilds at outdoor parks,” revisits my experiences with wild (non-human!) roommates and officemates in Rocky Mountain National Park.
