Kourtney Kardashian is doing her part to fight plastic pollution by launching a special $40 'Instagram-worthy' water bottle that she hopes will encourage her fans to stay away from single-use plastics.
The 40-year-old reality star took to Instagram to promote the new product - which is part of a collaboration between her lifestyle site Poosh and reusable water bottle brand S'well - while also celebrating the launch by posing for a stunning photo in a pool of water.
In the saucy snap, Kourtney can be seen lying back in the water, while modeling a sheer blue shirt, her wet hair left to dangle in the crystal-clear pool behind her.
In a stark contrast to the bright blue ensemble and the shimmering blue waters, Kourtney's eyes were shaded with a vibrant pink color, while the rest of her makeup was left natural - save for a nude color on her lips.
To protect her modesty in the snap, Kourtney modeled a bright blue tank under her sheer shirt, which was left to dangle in the water as she lay back and soaked up the sun.
Speaking out about the launch, Kourtney explained that she is making every effort to eliminate plastic water bottles in her own home so that she can ensure her children are able to enjoy the world's natural beauty for many years to come.
'Protecting our planet is more important now than ever,' she said in a statement. 'I want to do my part to make sure that our children have a beautiful world for years to come.
'We all have to take responsibility for our contribution - with each plastic bottle we use and throw away, we’re adding to an overwhelming funnel of pollution that goes into our oceans and destroys the environment.
'I’ve committed myself to removing all plastic water bottles from my home. Everyone that comes to my house is given a glass or S’well bottle to use, which was why I was so excited to partner with them for this launch.
'If everyone made the switch to reusable bottles, we could start to heal our world.'
Sharing the news of the launch on her personal Instagram page, the reality star-turned-lifestyle guru spoke in more detail about the motivation behind her decision to launch the water bottle.
'More than one million sea birds and 100,000 marine mammals are killed from plastic every year,' she wrote. 'Plastic is made to last forever, so it never goes away. The Poosh x S'well bottle will help reduce the amount of plastic we use, but we wanted to take action one step further to clean up our oceans.
'$20 of each bottle purchased will go to support Oceana and its campaigns to reduce plastic pollution and protect our oceans.'
Over on the official Poosh account, another post added: 'We’re practicing what we Poosh and doing our part to eliminate single-use plastic,' while the website tells its readers, 'This Instagram-worthy Poosh bottle will keep you hydrated while also keeping the environment healthy.'
The Poosh x S'well collaboration comes just as Kourtney soaked up some of the ocean's natural beauty for herself, sharing a video on her Instagram account that showed her modeling a sparkly purple bikini while lying in the water.
'Baby shark,' Kourtney captioned the photo, referencing the wildly popular kids' song that her own three children are no doubt big fans of.
The reality star has spent plenty of time by the water over the weekend, though this time she kept things closer to home, enjoying the comfort of her own pool.
