Vanessa Lachey is going to give her baby an environmentally friendly upbringing

The TV presenter is pregnant with her first child with her husband Nick Lachey and she is determined to live a green life for the tot.

Vanessa feels very strongly about environmental issues and wants future generations to inherit a world they can be proud of.

She said: "I definitely want to safeguard the future for my baby. I want to be health conscious for the baby. I`m learning about BPA friendly bottles. A couple have been sent to me and it`s great to understand that when plastics are heated, all the toxins [come out]."

"And even food. Things that are pumped with hormones. You actually, physically see the changes in a 13-year-old girl that was eating hormone food and a 13-year-old girl that was eating organic."

The 31-year-old beauty insists one small change everybody could make is to wash their clothes in cold water instead of hot.

Vanessa - who married Nick, 38, in July 2011 on Sir Richard Branson`s private Necker Island in the British Virgin Islands - says if everybody altered their laundry habits it would save enough energy to light up New York for "71 years".

Speaking to promote P&G`s new Tide Coldwater detergent, she told E! Online: "We use 80 per cent of our household energy to heat water. By saving energy, you`re saving money, who doesn`t want that? And lastly, you`re doing something good for the environment, so it`s a one, two, three punch.

"If everybody in the US just did laundry with cold water for one year, it could power the city of New York`s lights for 71 years. It`s crazy."
